SHUTTLE.

Application led August 28, 1911.

To all y07mm t weag/ conce/m."

Be it known that l, FREDERICK H. BEACH, a. citizen of the United States, residing at Batavia, in the county of Kane and State of Illinois, have invented new and useful lmproveniente in Shuttles, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide a loom shuttle of greater capacity and durability than thoseY now in use and also fitted with improved devices for holding the bobbin and for threading. i

It consists of the features and elements described and sho-wn in the drawings as indicated in the claims.

In the drawings z-Figure l is a top plan view of a shuttle embodying this invention. Fig. 2 is a medial section of the rear portion of the `shuttle taken as indicated at the line 2 2, on Fig. l. Fig. 3 is a transverse section taken as indicated at the line 3-3, on Fig. 2. Fig. il; is a side elevation of the shuttle illustrated in Fig. l. Fig. 5 is a detail perspective View of the bobbin holder. Fig. 6 is a section at the line 7-7 on Fig. 1. Fig. 7 is a section of the line 8 8 on Fig. 2. Fig. 8 is a top plan View of the shuttle slightly modified in construction. Fig. 9 is a section at the line 10-10 on Fig. 8.

rFhe shuttle illustrated in the drawings comprises a body which may be made of only two pieces, as shown in Figs. 9 and 10,

' but which may also be made as sho-wn in the remaining gures, consisting of two relatively thin full length slabs, l, and 2, and intermediate short blocks, 3 and 4f, at the ends. Each of the side slabs, l and 2, is suitably hollowed out on the surface which is to form the inner side of the completed shuttle. It will be noticed also that the shuttle is left open at the bottom, as seen at 7 in the drawings, for the entire distance between the interposed end blocks, 3 and 4, the width of the rift being substantially the thickness of said end blocks.

For proper operation in the loom, it is necessary that the bobbin should be centrally located in the shuttle cavityv and that its'aXis should be quite accurately in line with the guide about which theyarn runs to the eye, so that the thread may at all times draw alike from all sides of the bobbin as it unwinds. Whenever, by reason of any deficiency in the bobbin-holding means, the

bobbin leans to one side or the other, the yarn in running ofi" the end of the bobbin is liable to be bro-ken by the eXtra strain experienced in pulling it off at the side which is most out of line with the guide. Also, in lthe more common form of shuttles, the .bobbin holder is of such construction as to occupy very considerable space in the solid end portion of the shuttle, thereby limiting the length of the bobbin cavity in the shuttle. For overcoming. both of these defects, the shuttle shown in the drawings is adapted to receive a bobbin of ordinary construction,-consisting of a stem, 8, and a head or flange, Sa, having a peripheral groove, 8b, for holding the bobbin in the shuttle, by means of the following construction: The bobbin-holder consists of a U-shaped seat or stirrup, 10, adapted to engage the flange, 8a, of a bobbin at the groove, 8l. |This stirrup or holder is hung in the` shuttle body by a pair of lugs, l2, lodged in the upper face thereof and secured by screws, 13.

In the more familiar forms of shuttle, the bobbin is axially apertured and carried on a spindle mounted within the recess of the shuttle, while some form of catch is provided to engage a small portion of the peripheral groove, 8b, for retaining the bobbin upon the spindle. Experience has shown, however, that there is considerable danger of the operator failing to fully insert the bobbin into proper engagement, and also of the ange, 8a, splitting off back of the groove, 8b, at the point where it is engaged by such a catch, with the result that the bobbin is permitted to work o the spindle and often to fly out of the shuttle, becoming entangled in the warp and breaking the filling thread so as to cause damage and delay. The present form of holder, consisting of the stirrup, 10, by engaging the groove, 8b, throughout something more than half its circumference, so distributesv is adapted to seat against the flat end of the flange under the influence ,of pressure applied preferably near the center of the 2 plate, thus tending to make the pressure uniform around that part of the groove, 8b, which is in engagement with the holder, 10, and further serving to vkeep the bobbin properly alined with the shuttle; and this is further assisted and the bobbin is accurately centered, by providing a slightly tapered centering stud, 1s, on the plate, 1e, which engages the axial aperture of the bobbin.

To prevent the bobbin from becoming disengaged from the holder, 10, and escaping from the shuttle during the operation of the loom, there is provided a guard, 15, consisting of the guard plate, and a pair of bracket arms, 15, extending at vright angles thereto into a recess,-1b, in the rear end of the shuttle where they are pivotally secured upon the pin, 15C. rIhis adapts the guard to be raised upward to the dotted-line position illustrated in Fig. 2, so as to remove the guard plate, 15a, from its locking position directly over the flange of the bobbin, and permit the removal of the latter from the fastener, 10, for re-lilling of the bobbin, or any other purpose. The pivot pin, 15, is carried at one end Aof a spring, 16, secured V in the end `of the recess, 1", by a screw, 16a,

and, designed to institute a thrust longitudinally of the shuttle. T his thrust is communicated to the friction plate, le, through a link, 17, pivotally connected to the arms, 15", by a pin, 15d, and similarly yoked to the plate, 1e, upon a pin, 1st, carried in the lugs, 1li", extending rearwardly'from the back of the plate, 1e. As the guard, 15, is swung down to locking position, the link, 17, assumes a position just below Vthe line connecting the pins, 15c and 14a, and thus becomes an eccentric lock by virtue of the thrust of the spring, 16, for holding the guard, le, in Vthis position. Thus by the above described coordination of parts, there is produced a shuttle in which the bobbin is secured firmly and safely, though with the possibility of ready removal, and the safety of operation of the shuttle is considerably increased over that attending the use of the present familiar forms. Also this construction permits continued use of bobbins which may have had a. yportion of the flange broken, thus tending very materially toY increase the length of timethat they may be used before being discarded. It will lbe observed that in this construe tion the bobbin is positioned axially within the bobbin cavity'of the shuttle by the seating on the friction plate, 14, which is held accurately in position by thel thrust of the link, 17, on its flat cut end or bottom which is on the end of the grain of the wood of which' the bobbin is made, and therebyadapted to enduremaximum wear and pressure without being worn or forced out'ofv true plane. Also the devices for holding the bobbin are very much less in weight Y than `those commonly employed, in which there is a long spindlev carried by them onV which the bobbin is mounted. The light-- ness of the bobbin-holding devices obviates erally grooved bobbin base,

shuttle box, causing the Vshuttle often to be badly roughened or broken at that end. The bobbin-holder herein shown and described is but very little heavier vthan the amount of material removed from the shuttle body in order to receive said bobbin-holder, and. the shuttle is therefore left well balanced.V
